摘要

[目的

]

分析晋陕蒙接壤区1990—2020年水土流失年际动态变化情况及其原因，为该区水土保持工作的有效开展提供科学支撑。[方法

]

利用1999，2018，2019和2020年水土流失监测数据，获得4 a晋陕蒙接壤区水土流失动态监测成果，分析研究区水土流失年际间动态变化情况。并通过2020与1999年监测成果对比，进行动态变化及其原因分析。[结果

]

得力于国家和地方政府层面水土保持方针、政策、措施以及相关监管部门工作的有效落实，1999—2020年晋陕蒙接壤地区水土流失面积由4.71×10

减少至2.45×10

，减幅达47.98%。[结论

]

研究区1990—2020年水土流失强度明显减弱，由以强烈及以上侵蚀强度为主转变为以轻中度为主，生态环境显著改善。今后应根据区域水土流失特点，进一步加大投入和实施更有效的水土保持措施。

Abstract

[Objective] The interannual dynamic changes and causes of soil and water loss in the contiguous area of Shanxi

Shaanxi and Inner Mongolia during 1990-2020 was analyzed

in order to provide scientific support for the development of effective soil and water conservation in this area.[Methods] Based on the monitoring data of soil and water loss in 1999

2018

2019 and 2020

the interannual dynamic changes of soil and water loss in the study area were analyzed. By comparing the monitoring results in 2020 and 1999

the dynamic changes and their causes were analyzed.[Results] Due to the effective implementation of water and soil conservation guidelines

policies and measures formulated at the national and local government levels

the area of soil and water loss in the study area decreased from 4.71×104 km2 to 2.45×104 km2 during 1990-2020

reduced by 47.98%.[Conclusion] The intensity of soil and water loss in this area has been significantly decreased from strong and above erosion intensity to light and medium erosion intensity

and the ecological environment has been significantly improved. In the future

in accordance with the characteristics of regional soil erosion

further investment and more effective soil and water conservation measures should be implemented.
